    My Robustas are tall, leggy shrubs with leaves only at the tips of the canes and wicked thorns. The blooms repeat fairly well here near the Texas Gulf Coast but are fragile and shatter easily. They would be at their best at the back of a bed.

    Robusta left my garden due to the combo of truly wicked thorns and long leggy canes that wanted to spread and take up much much more room than I had given it. I did so just love, love, love the vivid red flowers that were exceptionally pretty. Yes, it blackspots very easily.
